Appeal No. 2002-0984
Application 09/246,179
the absorption of the reaction media, calculating the degree of
conversion based on the absorption values measured and modifying
or terminating the process when the desired effect has been
obtained.
Claim 6 is believed to be adequately representative of the
appealed subject matter and is reproduced below for a more facile
understanding of the claimed invention:
Claim 6. A process for the controlled production of
polymeric products and/or modification of polymeric products
comprising
a) determining characteristic IR absorption bands for the
starting material and the desired product,
b) determining the absorbance of the characteristic IR
absorption bands from a),
c) immersing an IR-ATR probe in an agitated reactor having
contents with a maximum viscosity of 10,000 Pas and flow
velocity of from 0.01 to 10m/sec at the probe location,
d) measuring absorption directly by means of the IR-ATR
probe at short time intervals during the production or
modification reaction,
e) calculating degree of conversion and/or degree of
modification of the reactor contents using one of the
following equations:
M(t) = 100 - A(t)/A(tO) ! 100 (%)
or
U(t) = 100 - A(t)/A(tO) ! 100
(%)
